Former 100m world record holder Asafa Powell withdrew from Monday’s historic Stawell Gift in Australia, citing the same hamstring injury that forced him out of the Olympic final last summer.

Now the Jamaican sprinter is out of an upcoming race in Melbourne, too. Powell was sore after a warm-up race Saturday in Victoria, where he finished third after being unable to run full speed.

He told the Stawell Athletic Club that he wouldn’t be able to compete on Monday, which earned him an automatic 14-day suspension, knocking him out of this weekend’s IAAF Melbourne Track Classic.

Powell, who has run more sub-10-second 100m races than anyone else in history but never earned an individual world or Olympics gold medal (BOLT!), will have an MRI Tuesday to determine the severity of the injury. But according to an interview that admittedly happened last week, the sprinter still thinks his best is yet to come.
